Effects of Biochar Amendment on Growth and Yield of Rice in Cold Water Field
摘要
Abstract
[Objective] Application effect of biochar on cold water field was explored,in order to provide scientific basis for the amelioration of cold water field.[Method] With the Dyou NO.202 as test material,set up 5 different application rate of biochar,field plot experiment was carried out to study the effects of biochar on rice growth and yield.[Result] The application of biochar could improve the cold water field soil temperature,promote rice growth,rice dry matter accumulation increased by 17.6％-22.7％ than CK; could significantly increase rice yield,compared with the control by 9.4％-19.7％.Regression analysis to calculate the maximum rice yield of biochar application rate was 2 238.8 kg/hm2.[Conclusion] Applied biochar could improve soil temperature,promote rice growth and dry matter accumulation,improve the absorption rate of nitrogen,phosphorus,potassium,increase rice yield.Biochar was an effective soil ameliorant of cold water field.关键词
